摘要
工程是体型复杂的空间钢结构屋盖结构,从屋盖的结构模型选取入手,深入进行了屋盖结构的线性整体稳定分析和大位移几何非线性整体稳定性分析,并对不同分析条件下、不同荷载组合下的稳定承载力进行了分析比较。
This project is a complex space steel roof structure.The structure model of the steel roof was selected.The linear overall stability analysis and the large displacement geometric nonlinearity overall stability of the roof structure were performed.The stability of the bearing capacity under different load combinations and different analytical conditions was compared.
